One of the leading suppliers and the manufacturer of the SS 347/347H flanges is the Metalloy Steel SS 347/347H is an alloy that is stabilized by columbium and tantalum. The components of this grade have a great affinity for carbon than chromium. Due to the high content of the carbon, this grade is suitable for use in the various industrial applications. We make the stainless-steel flanges for different industries and specialize in doing this work for a long time.
We make the flanges in the standard specifications or customized specifications as needed by the customers. Some of the properties of SS 347/347 H flanges is that they show improves resistance to corrosion as well as have high creep resistance features. These flanges are best for use in the application where there is continuous heating is required in the range of the 800-1650F.
Also, this grade shows useful mechanical feature at elevated temperature. These flanges are used in the aeroplane exhaust stacks, expansions joints, annealing box, collector ring, etc. We mainly manufacture SS 347/347H flanges in the form- forges flanges, socket weld flanges, welding neck flange, long weld neck flange, reduced flange, etc.
